Description
Technical field
The utility model is related to flow cytometer sheath fluid systems, and in particular to a kind of flow cytometer sheath fluid bucket low liquid level report
Alarm device.
Background technology
Sheath fluid system is the important component of flow cytometer, and the stabilization of sheath fluid seriously affects the reliable of experimental result
Property.The high-end stream type cell analyzer of LSRFortessa models of BD companies production is equipped with to ensure stable sheath hydraulic coupling
Stainless steel sheath fluid bucket.But due to being fitted without sheath fluid level detection alarm module, stainless steel on the circuit main board of this instrument
Sheath fluid bucket can not directly observe liquid level position again, the case where low liquid level is even run without sheath fluid often occur, do not simply fail to ensure
The reliability of experimental result is needed to take a long time stable fluid path, and can be caused to important component-flow chamber of instrument
It is badly damaged, bring expensive maintenance cost.
In order to solve these problems, producer suggests placing electronic scale under sheath fluid bucket, but this solution has much not
Just, it cannot effectively solve the above problems.For example, electronic scale can not show always weight, needs to lift in sheath fluid bucket and relay
It is lower to show number.In addition, equipment user long-time operation often forgets about the weight of observation sheath fluid bucket, still often occur
The case where low liquid level is even run without sheath fluid.Therefore, it is that stainless steel sheath fluid bucket installation low liquid level warning device is very necessary.
Utility model content
The problem of for the above prior art problem, the utility model proposes a kind of flow cytometer sheath fluid buckets
Low liquid level warning device.
The flow cytometer sheath fluid bucket low liquid level warning device of the utility model includes：It is host, floating ball, conducting wire, pipeline, right
Connector and sealing device；Wherein, floating ball includes buoy, annular magnet, nut and buckle, buoy inner hollow, in buoy
To have coaxial annular magnet, nut include the top connector that is connected as one and the internal column for being equipped with tongue tube for side
The Cylindrical joint of connector, nut passes through hollow buoy and its annular magnet of inside, the bottom end of Cylindrical joint to be fixed by buckle,
Buoy can float up and down along Cylindrical joint；Pipeline is with hardness and hollow tubular；The bottom end of pipeline passes through banjo fixing butt jointing
It is connected to the top connector of nut；Sheath fluid is held in sheath fluid bucket；The roof of sheath fluid bucket is provided with reserved opening；Bottom end is equipped with floating ball
Pipeline vertically place in sheath fluid bucket, buoy is suspended in sheath fluid；The top of pipeline is fixed and close by sealing device
Envelope；Nut connecting wire, conducting wire passes through the inside of pipeline, and the top for being pierced by pipeline is connected to host, and host is fixed on sheath fluid
On the outer wall of bucket, host, floating ball and conducting wire constitute liquid level alarm.
The annular magnet of side in buoy, if close to nut end, low liquid level warning；If close to buckle end,
Then high liquid level warning.The utility model is low liquid level warning, and annular magnet is located at nut end, and when liquid level declines, buoy is fallen
Contact buckle, triggering host alarm.
Pipeline uses, and there is hardness not deform upon and will not such as use stainless steel by the material of sheath corrosion.Pipeline
Length is 140~150mm；Internal diameter is 4~8mm.
The material of banjo fixing butt jointing uses metal.
The material of sealing device uses silica gel.
The advantages of the utility model：
The utility model provides a kind of low liquid level warning device for flow cytometer stainless steel sheath fluid bucket for the first time, using in
The bottom end of empty pipeline installs the buoy of floating ball, nut connecting wire by nut, and conducting wire is connected to liquid level warning by pipeline
The host of device, buoy are suspended in the sheath fluid in sheath fluid bucket, when the liquid level of the sheath fluid in sheath fluid bucket drops to the lowest order of setting
When, buoy drops to the position of buckle, trigger switch with liquid level, and conducting wire is connected to host and sends out alarm；The low liquid of the present invention
Position warning device is at low cost, effect is good, provides safeguard for the stable operation of equipment, there is good application prospect.
